A revision of the Indian species of Gonatocerus Nees (Hymenoptera: Chalcidoidea: Mymaridae)

Abstract

The Indian species of Gonatocerus Nees are revised. Thirty-nine valid species are recognized from India, including eleven species described as new in this paper. The Indian species are referred to three already known species-groups (ater-, sulphuripes-, litoralis-gioxips), and a new species-group (asulcifrons-group) proposed here for two Indian species. Separate keys to the species-groups and to species of three groups are given. The present study led to the proposal of 13 specific synonymies. Also five species are recorded from India for the first time, one species (kodaianus) described in Ooctonus Haliday is transferred to Gonatocerus as a new combination, and one species, G. longicrus Kieffer, is regarded as insertae sedis.
